Export to IGES or STEP with custom properties attached

Is there a way to have the custom properties from your SW model embed into an IGES or STEP 203 or 214 export? I am working on a customer process that requires traceablity to be imbeded in the exported files. Currently the only way I know to do this is to rename the file to a .txt, add the information I want as a header and then rename the file back to .iges or .step. Any help would be appreciated.

You can simply right click on the files and select open with and chose notepad. And in the window, select Notepad from the program list and also check "Always use this program to open the file". This way whenever you'll double click in the file, it will open in Notepad.
